Nasa's next Mars rover will be aimed at one of the planet's deepest craters.
MSL-Curiosity weighs almost a tonne and is the size of a Mini Cooper.
It will carry instruments to study whether Mars had the conditions in the past to support microbial life.
The US space agency has selected an equatorial depression called Gale Crater to investigate that question.
The $2.5bn rover will launch from Florida in November.
